[ODIN][GT-I9300-CHN]unbrick and convert CHN to EUR JB 4.1.1

Hi, many people brick their Galaxy S 3 model GT-I9300-CHN when they trying to updat it to the international firmware, as my friend did, and that doesn't work, because it has a different modem which is WCDMA, so I made odin rom from I9300XXDLJ2 with a modem.bin and boot.img from I9300ZCDLK1and the result was really successful! and I have the pleasure to sharet it with you at mediafire from hier.

Need some help!

I followed this post, which saved my phone from soft-bricking (Thank you!). But it now can't receive data with HSPA network. Is this the fabled broken modem?
I'm not sure how to fix this.. Is it possible to flash modem by itself? How do I know which modem works with HSPA?

I don't know what you did exactly, Do you have the international I9300 or the chinese I9300-CHN ?

I have the CHN version. When I was flashing the JB for international version, it always failed out when flashing 'radio'. Then I found your post and followed it. Now I have the stock 4.1.1, everything is working except HSPA data.

The problem is in the modem hardware, the I9300-CHN has a WCDMA modem which mean 3G and the HSPA is a 3.5G they are different, and you can't install HSPA software for WCDMA hardware it's like installing ATI Drivers for NVIDIA Graphic card!
The solution to me, is that you change your sim card to the carrier which support WCDMA or Change your mobile to a mobile wich suporrt HSPA.
I hope that make it clear.

CyanogenMod is not custom rom from the stock firmware its compiled rom from the android open source, the team develop their own drivers for the hardware, so you may try their modem and install it in clockworkmod recovery, but becarfull to the API level, modem from ICS 4.0 may not work on JB 4.1, so it's better to look in CyanogenMod 10.
I haven't the I9300-CHN to try this test, so I have the pleasure if you test it.

Hey meodroix, sorry I didn't get around to this ( was getting by with a CM10 build). I'm stuck: I read somewhere modem can be odin-flashed by putting the modem.bin file on 'phone' box.
In my case, HSPA+ network only works for me under CM ROMs. So I want to replace the modem you found with one in CM10. But CM10 (9 too) is only available in .zip package format.. Is there any way to compile modem.bin from part of the zip pack? Or I'm totally off track

First check your phone if it's really CHN by entering to download mod you will get "i9300_chn_chn" than try to install the original firmware after that install the modified firmware.
Bonne chance.

hi meodroix.. the result was really successful...im really appreciate it...just want to know if i can update to JB 4.1.2... i was traying with kies, but upgrade is not fount...thks for all..

No you canít update that using kies, because itís not original, itís a hybrid from too versions deferent, and to update to 4.1.2 we must create another one from the European and Chinese version of android 4.1.2 and that maybe in future, at this time enjoy 4.1.1

Re: [ODIN][GT-I9300-CHN]unbrick and convert CHN to EUR JB 4.1.1

Hello Meodroix, i'm having a hard time trying to get the files from mediafire.com, is it possible to grab the full file from someplace else?...if not too much to ask. I want to give it shot to your firmware version. Currently im running the Chinese GT-i9300 with CyanogenMod 10.1 and it works like a charm but i loose all the samsung goodies (allshare, dual view, remote control for other samsung devices, etc...) Thanks in advance.

Re: [ODIN][GT-I9300-CHN]unbrick and convert CHN to EUR JB 4.1.1

Meodroix, i've been doing some research trying to find out if there are other countries that have the same modem as CHINA and that we could use their ROM in our phones so we can get an orignal Samsung ROM and get updates using KIES but i haven't got any luck. Do you know if there's such thing?
